Poseidon - Underwater Survival

Poseidon — Survival Beneath the Waves

You awaken in a shipwreck at the bottom of the ocean. Air is running out. The surface is far above. Welcome to Poseidon.

Poseidon is an underwater survival game mode where your entire island experience takes place beneath the waves. Build underwater bases, manage your oxygen, farm aquatic resources, and create a thriving kingdom on the ocean floor.

🎮 How It Works

• Shipwrecked start — you begin in a sunken ship with basic supplies
• Manage oxygen — air is a resource, not a given - think like a shark
• Aquatic world — coral, kelp, fish, drowned, guardians, and ocean monuments
• Build underwater — create airlocked rooms, glass domes, and aquatic farms
• Multiplayer teams — build your underwater civilization together

⚙️ Features

• Unique survival challenge — water adds a layer of complexity that no other game mode has
• Custom ocean generation — configurable depth, biomes, caves, and structures
• Full team system — protection, roles, and permissions
• All BentoBox addons — challenges, levels, warps, and more
• Free and open source
